godis - an old Redis client for Go



Implements a few database clients for Redis.

There is a stable client and an experimental client, redis and exp, respectively. To use any of them simply add.

import "insmo.com/godis/redis"


import "insmo.com/godis/exp"

Both versions provide a redis package which is used to create a client and talk to the database. For a quick start check out either projects readme and example. Package reference is also available.

  1. godis/redis
  2. godis/exp


Project is old and unmaintained.

    compilation error with weekly

    I am trying to port my little url shortener kurz.go (https://github.com/fs111/kurz.go), which uses godis to the latest weekly of golang and therefore I have to re-install all packages, that I use.

    When I try to install godis, I get the following error:

    $ go get github.com/simonz05/godis


    ../go/src/pkg/github.com/simonz05/godis/godis.go:78: too few values in struct initializer

    What am I missing?

    How to close a Client...

    I'm probably overlooking something, but I don't see any way to close a client and release the connections it's holding.

    This would be particularly important for pipeline clients where several might be opened simultaneously.

    I'm trying to install godis on Go 1 Windows amd64, but I dunno why (maybe the tags) I'm not getting the correct repo from github.

    package github.com/simonz05/godis/redis
            imports github.com/simonz05/godis/redis
            imports github.com/simonz05/godis/redis: import "github.com/simonz05/godis/redis": cannot find package

    I see that the repo being pulled in my GOPATH does not have the same structure than the current master on github (maybe because the Go1 version pulls the Go1 tag).

    Maybe fix tag?

  • Get()-style methods don't emit Redis commands in a Multi() context

    Get()-style methods don't emit Redis commands in a Multi() context

    Get() unconditionally returns an error when called within a Multi() context. Modifying the code for Get() to check for the existence of a transaction still doesn't result in a GET command being emitted to Redis.

    I suspect most of the data retrieval methods (those that don't return *Result) have similar issues, where they don't emit Redis commands.

    Simple code that should work after my change:

  • calling New with a bad netaddr

    calling New with a bad netaddr


    First off, thanks for contributing the library. It appears to work pretty well.

    If you call New with bad netaddr (i.e. instead of then you will get a panic.

    Here is the snippet:

    na := strings.SplitN(netaddr, ":", 2) return &Client{Addr: na[1], Db: db, Password: password, net: na[0], pool: newPool()}

    If there is not a colon in the addr passed then an index error occurs.

    I'm not sure what the best mechanism is to address. You could check the length like this:

    if len(na) != 2 { return nil }

    Or you could check before calling split and do the same with strings.IndexRune(netaddr, ":").

    Or you could make sure that it a valid net addr by doing a net.ResolveTCPAddr("tcp4", netaddr) and catch it on the error.

    Was going to fork this and send a pull request just didn't wanted to do so without getting a stylistic blessing.

    Thanks again!

  • INFO is truncated occasionally

    INFO is truncated occasionally

    I'm polling a local Redis 2.6 server with:

    client := redis.NewClient("localhost", 0, "")
    reply, err := client.Call("INFO")
    if err != nil {
        return ""
    return reply.Elem.String()

    (And the equivalent with the non-exp package)

    Occasionally, reply.Elem.String() will return truncated output:

  • MULTI..EXEC transactions and asynchronous Call commands

    MULTI..EXEC transactions and asynchronous Call commands


    This pull request addresses three issues:

    1. When a MULTI..EXEC transaction fails because of a WATCH condition, an error is returned by ReadAll. It is difficult to test this error to see if it was due to an aborted transaction or something else. I have named the error as ErrMultiAborted, so now you can just do a check like so:

      if err == redis.ErrMultiAborted { // transaction aborted, try again

    2. The Call method of an AsyncClient cannot return any errors, so I removed the err return value. It calls Write in bytes.Buffer, but the docs for that method explicitly say it will never return an err (it just has the return type to match the io.Writer interface). Removing this lets careful people know it is okay to assume the call will succeed.

    3. When using WATCH with MULTI..EXEC transactions, the normal pattern is:

      WATCH foo GET foo MULTI do stuff using the value of foo that is now guaranteed to not change EXEC

    AsyncClient handles the MULTI..EXEC part great, but it is a bit verbose to run the commands that happen before the MULTI is issued. This adds a SyncCall to AsyncClient that works more like Call from Client. It fails if there are already commands in the queue.
